When spammers get whitelisted...

[Allie D.]

I have had to wipe my spamdb twice in the last month because spammers
get past my blacklists (I run the ones that come in spamd.conf) and my
greylisting and just hammer a few of my customers. The spam comes from
multiple IP's so it's a bitch to block by hand...anyone have any tips on
blocking these bastards ???
